A research team from POSTECH, KAIST, and Gyeongsang National University has developed an anode-free lithium metal battery that boasts a volumetric energy density of 1,270 Wh/L, nearly double that of current lithium-ion batteries. The innovative design allows lithium ions to deposit directly onto a copper current collector while employing a dual strategy to address dendrite formation and battery longevity. The battery demonstrated an impressive 81.9% capacity retention after 100 cycles and a Coulombic efficiency of 99.6%, highlighting its potential for commercial applications.
